Two different buffer sizes???

[JSmith1234567]

I've noticed you can set a buffer size in the Configure Hardware Driver window, but that is not reflected in the buffer-size setting in the Control Panel.

Basically you can have two completely different buffer sizes at the same time?

Does this make sense, or does anyone know the difference?

Does one over-ride the other?

Thanks!

Not possible here, what ever I change in the Configure Hardware window changes what appears in the Control Panel and vice versa. They are always the same. If they appear differently on your system, I suspect there is a problem.

They show the same on my system as well.

My interface is an Apogee Ensemble.

Are you all using MOTU hardware?

I'm guessing it's a screen redraw issue. If you change it in the control panel does the Audio setup change to match? Also check the software for the unit to see if it reflects changes you make.

Focusrite and RME hardware here.

I just realized it's the host-buffer multiplier.

I have it set at 4, which is what is doing it.

I know there has been allot of discussion about this, but I think I'll just have to load a really large, proccessor-intensive project and mess around until I find an optimal setting.

If I set 64 in The Configure Hardware Driver window, it changes to 256 in the Control Panel indicator.

How this all affects VI's I guess I'm just going to have to mess with.

FWIW, the host buffer multiplier is gone in 9.1.

Perhaps that doesn't affect you now, but it may in the future if you find an ideal setting and decide to upgrade.

[JSmith1234567]

I installed 9.1, tried it for two days, and went back to 9.02.

WAY too many problems to list here, but there were multiple.

I'm looking forward to 9.1x, but for now 9.02 is rock-solid and more efficient for what I do.

I emphasize "for what I do", for as they say on TV, your results may vary!

It's a bug. I saw this happen a couple of times when I selected two different interfaces. (Btw, ya'll did notice that Host Buffer Multiplier has been removed, right?), and then when I click OK the control panel didn't reflect the correct buffer size. For instance if I selected 1024 in the HW, then it would show 128 in the Control Panel.

I'm sure Mike has beat me to this , but is was most likely a bug the resulting from all the recent changes in DP's engine. I don't see the problem anymore, but just refresh the control panel to the right buffer setting until it reflects the correct buffer size.

By the way, if you're using Vienna Ensemble Pro, MIR and/or Kontakt it's my advice to set their buffers and CPU Threads to 0 and let DP control the whole show. I spent many hours testing this BEFORE all the new changes in DP and VEP (so perhaps my opinion may change later), and the best results occurred when 0 was selected. However, it's worth messing with Kontakt's Thread count to get a "level as possible" spread across the CPU threads.

If you have an external clock like I do, then .. even better.

Hope this helps..

There ya go. Just read this.

Btw, why not just set it as high as possible and let latency compensation do the work for you? Unless you're recording software instruments in realtime all the time then 512 will generally be fine, then just do any quick MIDI clean up. No reason to really go lower than that in my opinion. But if you must go low, at least VEP now has the deactivate feature just like DP does.

Make sure Kontakt is totally optimized for the session. It makes a huge difference.
